| | Speed Needed to Escape the Earth (Escape Velocity) |
 | | The escape velocity, as the minimum velocity that will allow a small body to escape from another body, can be calculated using the formula v = sqrt(2Gm/r), where G is the gravitational constant, r is the distance from the center of the body with a mass of m. |
 | | The speed needed to escape the earth or "escape velocity" is about 11,200 meters per second or 7 miles per second. |
 | | M is the mass of the earth, G is the gravitational constant, r is the earths radius, and v is escape velocity. |
